The Attempt at a Solution

Can someone tell me what values to plug in for the equation R/M integral (a+bT+cT^2...). The solution doesn't show this step, so I have no idea the numbers they used to get to 516.9 kJ/kg.

I know M is the molecular mass (44g), don't know R (universal gas constant, there are several), and as to the a+bT+cT^2+dT^3 from table D11 I plug in the values of a, b, c, and d for CO2, plug in 800K and 300K and do the integral and get something to the 19th power...which obviously is wrong. Any help would be appreciated. Thanks.

I'll bet you're reading the data wrong in ther table.

For example, d = 2.002 x 10^-9, not 2.002 x 10⁹.
